Are performance enhancing drugs (PEDs) an unnatural advantage? Sure. But so are many of the extreme training methods and nutritional regimens that are all now a regular part of almost all professional sports, including baseball. If PEDs were permitted, MLB could at least take the significant money it would save on expensive detection schemes, investigations, and mediation (players' unions don't tend to take kindly to 100-game suspensions) and use it instead to educate players about the health dangers of PEDs and the doses at which they are safest.
